CUTTING-MACHINE.

Patented Nov. 7, 1911.

Application filed June 16, 1909. Serial No. 502,546.

To all whom it may concern Be it known that I, FRANK MEYER, a citizen ofthe United States, and resident of Niagara Falls, in the county ofNiagara and State of New York, have made a certain new and usefulInvention in Cutting-Machines; and I declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it appertains to make and use the invention,reference being hadto the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part of thisspecification.

Figure 1 is a plan view, illustrating the invention. Fig. 2 is alongitudinal sectional view. Fig. 3 is a transverse section throughcutting roll f. Fig.4 is a transverse section through cutting roll 0.Figs. 5 and .6 are views of details. I

The invention has relation to cutting maparts of equal or nearly equalsize and similar dimensions, and designed to operate with a minimum ofwaste; and the invention consists in the novel construction and combi-,nations of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a,designates a frame having suitable bearings 12, in its sides forjournals or cutter rolls and gearing. The frame carries, at the feedend, a cutting roll 0, having a series of circumferential knivesdesigned to cut the material, which is usually submitted to the machinein sheet form, into longitudinal strips which are carried by an endlessbelt (Z, over the platen or bed 6, to a second cutting roll f, which isadapted to cut the strips transversely in such a manner as to subdividethem into tablets or small parts of about the same dimensions.

A comb or scraper g, is secured to the frame, and extends across thesame back of the cutting roll 0, its fingers engaging said roll so as todischarge the strips from the channels between the knives of said rolland cause them to fall upon the belt d, in longitudinal position andparallel relation to each -other,-such relation and position beingsuitable for feeding them to the second cutting roll f, whereby they aresubdivided trans--. 'versely. These cutting rolls 0, and f, are

shown extending crosswise of the carrier, and they are provided withgear wheels h, and la, respectively, which are operated by its frontedge.

vbeds without actual contact.

Under the cutting roll 0, is located a bridge-form cutting bed n, thetraveling belt being depressed at this point to permit its introduction.The upper or working surface of this bed plate is crowned or made convexand shelves off to thin edge to facilitate the passage of the materialto be cut.

The surface of the bed plate is provided with a series of grooves toallow the passage of the disk knives 2, and to effect therewith ashearing action. In front of this cutting 'p1ate, and under the belt maybe provided a transverse rise to guide the sheet of material upward andforward upon said cutting .plate, and in order to deflect the carrierbelt under the cutting plate, guide rolls t, are employed. Under thesecond or cross-cutting roll 7, is also located a transverse cuttingplate or bed a, of general wedge-like form, having a concave upper faceshelving toward This plate bridges over the carrier belt under thecutter and serves to cooperate with' the cutting roll in its action andto facilitate the movement of the subdivided material in the discharge.A slight adjustment of this wedge-form cutting plate is provided for byhaving its holding down bolts pass through slotted holes, and adjustingscrews to set it up. In front of this plate under the carrier may belocated a rise to facilitate the feed to the plate. In the rear of thesecond or cross-wise cutter f, is located a transverse stop guard orfender plate w, which is designed to check the flying particles orpieces as they are discharged from the second cutter and, cause them tothe reception of bolts whereby they may be upon a mandrel 6. Thiscorevis provided" with a circumferential series of straight grooves 7,which extend radially inward from the cylinder surface ofsuch.body.roll,

" between each two knives.

being separated by intervals, which are made of about the same width asthe spreader disks of the first or strip cutting roll 0. In thesegrooves are located knives 9, of straight elongated form, said knivesextending crosswise the direction offeed, and having at their ends.shouldered projections or tangs 10, adapted to engage holding rings orbands 11, on the shouldered ends of the.

body core, which secure the knives in place. At the ends of this bodycore are annular cam guides s, which are secured to the framing, andareprovided with eccentric or cam grooves j. I I v Between the knives 9are located the transverse ejector bars z,.sucl1 a bar being placedThese ejector bars are long enough to have their ends extend to engagethe cam grooves j, of the cam guides s, and said cam grooves arecentered high in order to draw the ejector bars in during the cuttingactions and push them outward intermediately, sothat they are given aradial'reciprocating action whereby the cutting operation is facilitatedand the discharge of such tablets or pieces of material as may be heldbetween the cutting blades is effected in a positive manner.

The operation of the machine is as follows: The material, which may be asheet of cerealfood stuff, is fed to the machine by being placed on thecarrier belt, whereby it is moved to the first cutting roll, where thesheet is engaged between the disk cutters of the roll and the cuttingbed plate below and is divided into strips which are discharged frombetween the knives by the comb fingers, and fall on the carrier wherebythey are fed to the crosswise cutting roll, and are subdivided by itstransverse knives and the concave bed plate into pieces or tablets whichare dischargedby the ejector bars upon the carrier belt, and conveyedaway thereby for packing and transportation.

Having described the invention, what I claim and desire to secure byLetters Patent 1s 1. In-a cutting machine, the combination with acarrier and a bridge cutting bed over said carrier of a cutting rollhaving a series of knives, ejector bars between said knives, and meansfor operating said ejector bars.

2. In a cutting machine, the combination with a cutting roll havingtransverse knives and reciprocating ejector bars, of a carrier,

a bridge-form cutting bed, and means foroperating said cutting roll andejector bars.

3. In a cutting machine, the combination with a cutting roll havingtransverse knives and reciprocating ejector bars, of a carrier, a bridgecutting bed, and means for adjusting said bed.

In testimon whereof I afiix my signature, in presence 0 two witnesses.

FRANK MEYER.
